3D Print Ultra-High Performance Concrete (UHPC)

With the introduction of 3D printing technology, a new era of the construction industry can finally be formed! Traditionally, buildings are constructed by using wooden formwork as a mold to hold the concrete. However, engineers started researching ways to implement 3D printing technology into the construction industry, which would help reduce the waste of wood and shorten the construction time. So far, little research on 3D-printable Ultra-high Performance Concrete (UHPC) is done, and our project is to help with the research. We are designing some concrete mixes that are 3D-printable. We check their fresh state properties like workability and printability, as well as their hardened state properties such as compressive strength. We have successfully printed some models, and we are looking forward to promoting 3D-printable UHPC for the construction industry to use.
